I need to generate doc (real doc, not docx) files, the "best" way i have found is to use word automation (Word 2010). I have files that I open, and then replace values inside before saving it on a new name. (Ex : I replace "" with "155023"). To do this, I use the Application.Selection.Find. I just had a problem when the new value had more than 255 characters (Thanks Microsofts limitations ...). To avoid this problem, i use TypeText in this case. My problem now is once I use TypeText, the Replace do not work anymore .. And I can't find why. Any idea will be greatly appreciated.

My code is in a function, called in a foreach with each values to replace :

private void Replace(Application app, string name, string newValue)
{
    Selection selection = app.Selection;
    Find find = selection.Find;
    Replacement replacement = find.Replacement;

    find.ClearFormatting();
    find.Text = "<" + name + ">";

    // Word limitation : can't replace with more than 255 characters, 
    // use another way to do it if that's the case
    if (tempNewValue.Length < 255)
    {
        replacement.ClearFormatting();
        replacement.Text = tempNewValue;
        find.Execute(Replace: replaceAll);
    }
    else
    {
        while (find.Execute())
        {
            selection.TypeText(tempNewValue);
        }
    }

    Marshal.ReleaseComObject(replacement);
    Marshal.ReleaseComObject(find);
    Marshal.ReleaseComObject(selection);
}
